Cleaning device with tail swab

ABSTRACT

A cleaning device with tail swab having a plurality of soft elongated strips.

FIELD OF INVENTION

The present invention generally relates to a cleaning device having anelongated tail swab that is especially useful for cleaning surgicalinstruments and medical devices. More particularly, the presentinvention relates to a cleaning device which includes an elongatedflexible leader member, a tail swab having a plurality of soft elongatedstrips attached to one end of the leader member, and a polymer materialcovering at least a portion of the tail swab and the end of the leadermember where the tail swab member is attached to the leader member.

BACKGROUND OF THE INVENTION

Medical devices and medical instruments are becoming more sophisticatedand much smaller thereby enabling surgeons to reach remote parts of thebody without the need for open surgery which exposes a much larger partof the body to the risk of outside infections. In addition, using theseinstruments results in lowering the complications of surgery andspeeding up the recovery time for patients. However, these devices andinstruments must be cleaned and decontaminated after use so that theycan be reused in future procedures. This cleaning and decontaminationprocess is often called reprocessing.

Reprocessing medical instruments and devices can become difficult withthe newest and latest devices which often include miniscule channels andcrevices that can be impossible to see and troublesome to access. Inaddition, the instruments and devices sometimes fail to come withadequate cleaning instructions or include cleaning instructions that areconfusing and onerous to follow. As a result, many of these instrumentsand devices are reused without proper cleaning which can lead to severerisks for patients.

A University of Michigan study analyzed the cleanliness of 350 suctiontips used to vacuum up fluids during surgery and found that 95 percentof them still contained debris after routine reprocessing. In anotherstudy, the Centers for Disease Control (CDC) conducted an investigationinto seven individuals who contracted surgical-site bacterial infectionsafter having knee or shoulder arthroscopy in a Houston hospital. The CDCfound that the arthroscopic shavers that were used for the procedurescontained residual bits of body tissue. Endoscopes and cannulas are evenmore worrisome to infectious disease experts in that millions ofsurgical procedures are performed each year using these instruments.

Surgical instruments like endoscopes and cannulas are typically cleanedwith twisted metal wire brushes and pipe cleaning type devices. However,these types of cleaning devices can cause major problems includingincomplete cleaning, damage to medical devices and instruments resultingfrom scratching, and metal fibers and other types of cleaning fibersleft inside the instruments after cleaning. In addition, these types ofcleaning devices are high in cost to produce and therefore need to bereused, thereby carrying the attendant risks of cross contamination.

Accordingly, there is a need for a simple, low cost cleaning devicewhich overcomes these obstacles. There is also a particular need for asimple, low cost device specifically designed for cleaning medicalinstruments and medical devices such as endoscopes and cannulas withoutthe risk of damaging the instruments and further risking infection topatients.
